This document contains a history of the development of mass concrete practice and discussion of materials and concrete mixture proportioning, properties, construction methods, and equipment. It covers traditionally placed and consolidated mass concrete and does not cover roller-compacted concrete.
Review the following publications for additional information, considerations, and approaches for mass concreting. ACI 207.1 – Guide to Mass Concreting. ACI 207.2 – Report on Thermal and Volume Change Effect on Cracking of Mass Concrete. ACI 207.4 – Cooling and Insulating Systems for Mass Concrete.

Calculate the section properties of a concrete masonry assembly constructed with hollow 8 in. x 8 in. x 16 in. nominal dimension concrete masonry units. The units have two face shells that are both 1.25 in. thick and three webs that are all 1 in. thick.
Table 2 lists calculated U-factors and R-values of various thicknesses of concrete masonry walls, for concrete densities of 85 to 135 lb/ft3 (1,362 to 2,163 kg/m3), with various core fills.
This guide reports data on the thermal properties of concrete and masonry constituents, masonry units, and systems of mate- rials and products that form building components.
These sections cover materials and proportioning of concrete; reinforcement and prestressing steel; production, placing, finishing, and curing of concrete; formwork performance criteria and construction; treatment of joints; embedded items; repair of surface defects; and finishing of formed and unformed surfaces.
